The microwave spectrum of N-methyl morpholine has been investigated within the 8 to 40 GHz region. The observed rotational constants for the ground vibrational state are (in MHz), A = 4821.235(0.077), B = 2342.579(0.004), and C = 1719.452(0.003). The dipole moment components have been determined as (in D), μa = 1.21(0.02), μ c = 0.10(0.03), and μ= 1.21(0.02). The values of these parameters show that the observed spectrum is due to the chair form with an equatorial methyl group. The 14 N nuclear quadrupole coupling constants have the values (in MHz), χ aa = 2.4(0.1), χ bb =.6(0.3) and χ cc = −5.0(0.2). Sets of rotational transitions due to six excited vibrational states have also been assigned.
